IS F (2008-2014) :: Burble / Popping Out Of Exhaust When Shifting At Certain RPMs
Jun 22, 2016
So I just wanted to ask 2 things.. Am I the only person who purposely shifts at certain rpms from 1st-2nd just to hear the burble/popping out of the exhaust.. I hold it around 3k and the shift and let off the gas and it's a Orchestra of amazing noises that are Oh so addicting. Secondly, are there any negatives to doing this... Or that sometimes I hear the loud thud/pop when slowing down but not every time... What is the true cause of these glorious noises.

Just wondering how to get my VR to pop, and burble like my old turbo jetta GLI with Milteek non resonated exhaust. One of the things I miss about my GLI is the popping I would get sometimes between shifts and on deacceleration in lower gears. How to get our engines to pop and burble like the turbo cars do. Is it just a free flowing catback like GHL, Neuspeed? Or is it the free flowing cats, or the turbo?

I installed the TurboKits CAI kit a few weeks ago. Installation went smoothly, and the latest kit has a modification to the box that fits our Accent's air snorkel. On cars with automatic transmissions, I had to cut out a notch from the bottom of the box to clear the transmission, but I doubt that this affects the air flow to the filter.
However, I have a big problem with the sound. The transmission often shifts at very low RPMs, and the CAI makes a very loud burble when this occurs. If I shift into a lower gear using the semi-manual mode, then the sound goes away. I realize that CAIs make a louder sound when you put your foot into it, but I find the sound a little over-the-top (especially considering that when the sound comes on, the engine is producing very little power at this part of the power band).
So, it's not really a problem with the CAI itself, more with the car's TCU. Unfortunately, it's too annoying for me, so I'll be reverting back to the original air intake system, and selling the TurboKits CAI.

All I did was cut off the straight section of tailpipe and install a 2.5" inlet, 4" outlet exhaust tip. It sounds a bit deeper at idle and a little louder when I rev it, but when I let off the gas it pops pretty loud.
I remember hearing popping on decel on videos of trucks where aftermarket exhaust/mufflers were installed, but not just from a new tip.

Used to own a F250 so I am new to the F150. I am currently in a 2014 F150 fx4 with about 10k miles on it. I noticed when the truck is shifting into 3rd (normal acceleration)the rpms once in third remain around 1800 then drop to 1400ish after about 2 seconds or so while still in third (almost like its shifting again). What it is?

I recently noticed my brand new truck with 5k miles has been making a humming /vibrating noise when shifting and when RpMs are above 2k. What this could be? It's a 2014 F150 stx 3.7 ....

Getting backfire or popping noise after deceleration with our cars. It didn't do it before with oem exhaust, just wondering if we're going to get a little bit from my new joe z exhaust, or do I have a leak somewhere with my installation. Or do I just need it break in a little more. How do I check for leaks , Do I just need to ramp the car and check all the flanges for where the exhausts bolts up and check for alignment issues.

So I bought LOLM3's old Borla a while back & everything's been great except CEL P0137 & the VSC light keeps popping up on me every 30-40 miles. I have a 12' with 20k miles on the odo.
P0137: O2 SENSOR CIRCUIT LOW VOLTAGE (BANK 1 SENSOR 2)
It has secondary cats welded on along with these type of O2 defoulers so the O2 sensors can reach the re-located bungs (except they're welded, not screwed on):
I've swapped sensor 1's with bank 2's sensor & even went ahead & replaced it with a brand new one, same code keeps popping up . Resetting the light is getting old & inspection time is coming up!
There are no audible exhaust leaks as far as I can tell, would a minor leak throw the CEL?Should I cut out the secondary cats & replace with straight piping like how the exhaust was originally made?

Ok, so in M mode shifts can be a little rough from 2nd to 3rd unless I give it enough gas. It's no big deal and my car has always been like that (owned it since 9/2013). But as of yesterday, shifts have completely changed from 1st to 2nd. It is clunky, extremely quick and lurches forward every time in M mode. It has NEVER done this before and it kinda sucks.
I've read all of the threads regarding tranny fluid, belt squeak, etc. and haven't specifically found anything like this. I haven't done anything to the car except the ELF recall and an oil change about a month ago.

Went to a road course for the first time on Sunday. After about 10 laps the car started smoking bad from the exhaust. The smoke was thick and white. There were professional drivers present (driving school) as well as a lexus service manager there looking at the car after the run. The smoke was thick but without that sweet smell of coolant. This was the hardest the car has ever been run but also maintained normal oil and coolant temperatures. After a bit of resting the smoke cleared up and never came back, my drive home was 2 hours long and car still seems ok. Engine sounds good, oil very clean, what could it have been? I have no cats so its going to be more obvious than normal.

My 2011 ISF has around 50K miles. Recently I noticed that when I shift into 1st from 2nd, usually on approach to a slower curve or slowing down to a light, there appears to be a distinct shudder. It doesn't happen all the time, and it happens regardless of Sport or normal mode.
Right after it shifts to 1st and the RPMs climb (or so it seems), I get 3-4 distinct back and forth movements .. i.e shudder. I think this is a recent phenomenon, as I know shifting into 1st is usually not very smooth, but I don't think I felt this shudder before.
No codes etc ...everything else normal. Don't think the trans is slipping, as car pulls hard and traction control is always busy. Motor mounts? Car is never tracked and driven spiritedly, but never ever abused or tracked. I do enjoy shifting it.

Any way to remove the "beep" sound at redline? i love that it shows the yellow yellow then red but the beep can get annoying.

Having a sound from my exhaust. Basically when the car is rolling along around 25 MPH or so, and my foot is not on the gas, as soon as I gently touch the gas pedal, I get a soft "thump" sound. This basically tends to happen in 5th or 6th gear only.
The previous owner had done a muffler delete on the stock exhaust so I figured there was some sort of back pressure issue because of this.
Finally out of frustration, I sprung for a new Borla Catback exhaust system, hoping to eliminate this issue. While the thump sound is slightly less, it still happens!

I have a 2008 is-f. My car will not rev about 1500 rpms and the hazard exclamation mark symbol is blinking on my dash saying check vsc! I had a bad battery and thought with the little research I have done that might be the problem but I put a new one in and the problem is still there. i own a scan tool so I scanned the cel and came up with code p2118 , it has to be something with the throttle sensor or something. I've tried pulling fuses and resetting the ecm but still no luck. I reset the cel with my little tool but it comes right back on as soon as its started.

Been researching exhausts a bit and getting information about the full PPE header and PPE Dual mode exhaust to review?

I have a question with aftermarket exhaust (particularly JoeZ and Borla) I was wondering after you installed the exhaust do you now get increased exhaust fume smells in the cabin when the windows or moonroof is open? When I had my 350(F-sport exhaust) I couldn't cruise with the moonroof open without filling the cabin up with fumes.

So I believe I have a crack in the Exhaust Manifold... When I rev the car I can hear a slight tick. I had taken it to a shop to do a muffler delete and said that there may be a leak or crack somewhere. The tech said it wasn't too bad but it may be something to keep an eye on. My question is, what would be the best route to go? Is this a common issue with the ISF? I was thinking if it was also possible if it may just be the gasket, which the tech also said it could be. I have a 2008 model with about 113k miles on it.

Car is:
1) Warmed up
2) At a standstill
3) In manual mode, 1st gear
4) Traction control is on/normal
5) Sport mode is on/off (doesn't seem to matter for this example)
How to verify:
1) Hit gas, more than 3/4 down
2) Shift above 5500rpm
3) As transmission up-shifts a drive belt squeal is heard.
4) Car otherwise accelerates normally.
This happens on two IS-Fs I've driven, a 2009 and a 2010, with or without the AC on. Is this a common issue? If so, what belt is slipping?

just recently installed the new X force exhaust system on my 2008 ISF with 72,000 miles on it. I've had the exhaust on the car for about 300 miles it when I was driving home from work today the vsc and check engine light pops up. I turn the car off when I got home and then turned it back on the check engine light was off but the stored Code was still there when I read it with the scanner P0420. I'm thinking maybe there's an exhaust leak even though it sounds fine.
